I. Introduction

A. Overview of Bootstrap and its components

Bootstrap is a popular front-end framework that helps developers create responsive and mobile-first websites quickly. It is structured around a grid system and comes packed with several reusable components such as buttons, forms, and navigation elements.

B. Introduction to List Groups

List groups are a flexible component that displays a series of content in a list format. They can be used to represent actions, navigation links, or more complex data collections.

II. What is a List Group?

A. Definition and purpose

A list group is a collection of list items that can be grouped together to display related information. They are typically structured using HTML <ul> or <ol> tags, styled with Bootstrap classes, and come with a wide range of functionalities.

B. General uses in web development

List groups can be used in various contexts, such as:

• Navigation menus
• Task lists
• Information display (e.g., contacts, products)

III. Basic Example

A. Structuring a basic list group

To create a basic list group, you need to use the Bootstrap class .list-group along with the .list-group-item class for each item in your list.

B. Code example

    <a href="#" class="list-group-item list-group-item-action">Morbi leo risus</a>
</div>

IV. Contextual Classes

A. Explanation of contextual classes

Contextual classes in Bootstrap let you style your list group items based on the intended action or category. They change the background and text colors, making it easier for users to identify different types of information.

B. Code examples for different contexts

    <a href="#" class="list-group-item list-group-item-success">Success item</a>
    <a href="#" class="list-group-item list-group-item-info">Info item</a>
    <a href="#" class="list-group-item list-group-item-warning">Warning item</a>
    <a href="#" class="list-group-item list-group-item-danger">Danger item</a>
</div>

V. Links in List Groups

A. How to use links within list groups

You can easily convert items in the list group into links that navigate users to different pages or sections of your site. This is done by using the <a> tag with the appropriate Bootstrap classes.

B. Code examples with links

<div class="list-group">
    <a href="http://www.example.com" class="list-group-item list-group-item-action">Visit Example</a>
    <a href="http://www.example2.com" class="list-group-item list-group-item-action">Visit Example 2</a>
</div>

    <a href="#" class="list-group-item list-group-item-action disabled">Disabled item</a>
    <a href="#" class="list-group-item list-group-item-action">Active item</a>
</div>
